砂层地质条件下大直径钢护筒定位下沉施工技术

Study on Construction Technology of Sinking Sand Geological Conditions of Large Diameter Steel Tube Location

结合石首长江公路大桥主墩大直径钢护筒定位下沉施工技术实例,总结施工经验,分析导向架的设计及施工流程以及钢护筒制作要点,实际效果良好,可对同类桥梁施工提供借鉴。

Combined with the main pier Shishou Yangtze River Highway Bridge of large diameter steel tube on the orientation of the construction technology of sinking,summarize the construction experience,the design and construction process of the analysis guide frame,and the main points of the steel barrel,the actual effect is good,to provide reference for similar bridge construction.
